SAUSAGE-STUFFING MACHINE.

No. 859,192. Specification of Letters Patent. Patented July 9, 1907.

Application filed May 2, 1905. Renewed June 3, 1907. Serial No. 377,043.

To all whom it may concern:

Be it known that I, Janus T. BARBER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Sausage-StuffingMachines, of which the following is a specification.

My invention relates to certain new and useful improvements in sausagestuffing machines, and contemplates a construction in which means areprovided to stop the machine automatically in the event of the supply ofmeat in the feed cylinder becoming exhausted, and independent means areprovided to stop the machine by manually closing the filling valves. Inaddition to the automatic and manual control of the operation of themachine, I provide means by which the direction of the feeding plungeris automatically reversed when the said plunger reaches the limit of itsvertical movement in either direction.

More specifically the means for stopping the operation of the machinecomprises a series of sliding detents normally engaging a belt shifterto hold the belt upon the drive pulley, which detents are automaticallyoperated by the piston in the event of the material in the feed cylinderbecoming exhausted before the skins are filled, or manually operatedfrom the filling cocks to release the belt shifter and stop the machinewhen the skins are filled before the supply of material in the feedcylinder is exhausted.

Still another object is the provision of means whereby the speed of themachine may be increased or decreased at will, such means embodying aduplex series of drive sprockets arranged in respective correspondinglyincreasing and decreasing order of sizes, and a chain trained over apair of said sprockets, one in each series. One series of sprockets iskeyed upon a sleeve, rotatable with the drive shaft, said sleeves beingmounted concentrically upon a rod joru'naled on an eccentric axisbetween the cylinder and the supporting bracket. Thus by turning saidrod upon its eccentric axis, the said'series of sprockets mountedthereon will be raised or lowered as the case may be to facilitate theremoval of the chain in changing from one pair of correspondingsprockets to another. I

The detailed construction will appear as the description proceeds,reference being had to the accompanying drawings, in which:

Figure 1 is a vertical section showing the operating" mechanism and theconstruction of the feed cylinder Fig. 2 is a top plan view; Fig. 3 is atop plan view of the lower section of the feed cylinder showing thearrangement of the operating levers and rods, Fig. 4, a view inperspective of the bell-crank lever for oper-' ating the belt shifter,Fig. 5, a similar view of the bellcrank lever for simultaneously raisingthe detents, Fig. 6, a similar view of one of the bell-cranks-foroperating an individual detent, Fig. 7, a view in elevation of one ofthe detents, Fig. 8, a perspective view of the clutch operating frame,Fig. 9, a fragmental perspective view of the detents and individualoperating means, andFig. 10, a detail view of one of the rod couplings.

The feed cylinder A, is formed in three sections 1, 2 Iand 3, securedtogether by suitable clamps, the operating mechanism being located inthe section 1, the section 2 containing the meat, and the section 3comprising a lid which is hinged in a'manner to be doscribed to thesection 2'. The section 1 is bottomless and is provided at its base withan annular flange l, by which the machine is clamped upon a suitable bedor table.

An L-shaped bracket 1 is mounted upon one side of the casing, and ahorizontal rod 4 has its eccentrically disposed reduced ends i journaledin said which rod, as intimated above, to be more fully explainedhereinafter. A sleeve 4* is frictionally mounted upon said rod anddisposed in concentric relation thereto, the drive pulley l andloose'pulley 4 being mounted upon one end of said sleeve in the wellknown manner, and a plurality of sprockets 4, graduated in size, beingkeyed upon the other end thereof and rotating therewith. I

The section 1 is provided at its upper end with a .web 2, extendingtransversely thereof, and of an inverted Ushape in cross-section, whichserves as a bearing for certain parts of the machine as will be morefully pointed out.

A transverse shaft 5 is journaled in the section 1, adjacent the base,the end of said shaft extending beyond the cylinder a short distance inorder to accommodate a plurality of sprockets 5 rigidly mountedthereupon, corresponding in arrangement to the sprockets 4 but graduatedin opposite order thereto.

A pair of oppositely disposed stub-shafts Gand 6, have their respectiveends journaled in the casing 1 and the adjacent side of the web 2, theseshafts being located in opposite sides of the cylinder, and beingdisposed in vertical alinement with the shaft 5 and parallel thereto,the shaft 6 carrying the sprocket 6 and the shaft 6*, the sprocket 6.Relatively corre spending sprockets 5 and 5, are mounted within thecylinder A upon the shaft 5.

The sprockets 4 and 5 are connected by a chain 7 and the pairs ofsprockets 5 and 6 and 5 and 6, are connected by chains 7 and 7,respectively, the chain 7 being partly broken away to show the automaticbelt-shifting mechanism. Bevel pinions 8 and 8 bracket and the wall ofthe cylinder, the purpose of are loosely mounted upon the ends of theshafts 6 and 6 respectively, these pinions having formed integraltherewith stationary clutch members, respectively 9 and 9. Correspondingclutch members 10 and 10, are keyed upon the shafts 6 and 6, but arecapable of limited reciprocatory movement to engage or disengage therespective clutch members 9 and 9.

A bevel pinion 11, in mesh with the pinions 8 and 8, is rotatablymounted in the web 2, and is formed with a central opening through whicha screw rod 12, provided at its upper end with a piston 12, equaling insurface area the interior of the cylinder, extends, said opening beingformed with internal threads, corresponding in pitch to that of thethreads of the screw rod 12.

The means for engaging the corresponding adjacent pairs of clutchmembers above referred to comprises a frame 13, of substantialrectangular contour, and having positive connection at its ends with themovable clutch members of each pair.

The frame 13 extends through the web 2, is slotted to permit a freelateral motion of said frame. The latter carries between the sides ofthe web 2, oppositely arranged downwardly extending arms 13, lying inthe same plane, and disposed at an angle to the frame, so as to presenttheir lower faces inclined. A pair of oppositely disposed lugs 13,provided with an inclined slot 13 are mounted upon the frame adjacentthe arms 13. The web 2 is provided with a pair of oppositely disposedapertured lugs 2 arranged on each side of the bevel pinion 11, the lugs2 serving as bearings for a pair of oppositely disposed Weighted levers14, which duplicate one another in construction and operation. Eachlever 14 has pivotal connection with the adjacent lug 2, at anapproximately central point, and at its upper end is provided with aweight 14, the lower end having loose connection in the slot 13, withthe lugs 13. The lever 14 is provided adjacent its intermediate pivotalpoint with an angularly disposed arm 14, possessing an arc-shapedcurvature or cam-shape, and normally lying on the same side of themachine as the arms 13, of the frame 13.

The screw rod 12 carries at its lower end a pair of oppositely disposedlaterally extending pins 12, for engagement with the aforementioned arms13, and at its upper end a pair of oppositely disposed laterallyextending pins 12 for engagement with the arms 14 The sectional view inFig. 1, shows the screw rod 12, with the pins 12 and 12 in frontelevation. Hence as this view is taken, on'ly one pin of each pair isvisible.

The elements above described constitute the operating mechanism. Poweris transmitted from a generator by a belt 4 to the fixed pulley 4, thesleeve 4 and sprockets 4, keyed upon said sleeve and rotating with saidpulley 4. By virtue of the chains 7 trained over the sprockets 4 and 5,rotary motion is imparted to the shaft 5, and oppositely disposedsprockets 5 and 5, and through the medium of the chains 7 and 7, and therespective connecting sprockets 6 and 6 to the stub-shafts 6 and 6 andmovable clutch members 10 and 10 keyed thereupon, and rotatabletherewith.

I have arbitrarily chosen that the piston and screw rod be fed upward bythe gears upon the left hand side of the cylinder, and downward by thegears upon the right'hand side. The left hand sprockets 5 and 6 arewhich of equal size, but the upper right hand sprocket 6 is much smallerthan its corresponding sprocket 5, in order that the screw rod 12 may befed downward in its return to initial position at a much greater degreeof speed than in its upward movement.

As shown in Fig. 1, the left hand clutches are engaged and the pistonhas completed approximately half the distance of its upward travel. Atthe termination of its upward movement the pin 12 will engage the arm13, thereby moving the frame 13 to the left, and swinging the weightedlever 14 to the right until the latter reaches a point just beyond itscenter of gravity, when the weight 14 will act to draw the lever 14still further to the right, and move the frame 13 as far as possible tothe left to disengage the clutch member 10 from the member 9, and engagethe right hand clutch member 10 with its opposing member 9, therebythrowing the right hand system out of gearing into operation, reversingthe direction of movement of the pinion 11, and feeding the screw 12downward. During the downward travel of the screw 12, the weighted lever14 will incline to the right and present the arc-shaped arm 14 in thepath of the pin 12". At the completion of the downward travel of thescrew 12, the pin 12 will engage the arm 14, thereby throwing theweighted lever to the left to a point just beyond the center of gravity,when the weight 14 will act to draw the lever 14 as far as possible tothe left, and at the same time that the weighted upper end of the lever14 is moving to the left, the lower end will be moving to the right,sliding the frame 13 therewith to disengage the clutches 9 and 10, andengage the clutches 9 and 10, thereby throwing the left hand system ofgearing into action to feed the machine upward, when the operationsabove described will be repeated. However, the movement of the screw rod12 is not continuous since the piston 12, upon its restoration to itslowermost position, operates an automatic belt-shifting mechanism, to bedescribed, to shift the belt from the fast pulley to the loose pulleyand stop the operation of the driving gear in order that the section 2may be refilled with meat.

A hand lever 4 is mounted upon the outer end 4 of the rod 4, upon theexterior of the bracket 1 by virtue of which the rod 4 may be turnedupon its eccentric axis to raise or lower the series of sprockets 4 inshifting the chain 7 from one pair of sprockets to another in ascendingor descending series of graduations. The lever 4 is provided with ashort depending arm 4, engaging a stop 4 provided upon the bracket 1",to prevent the accidental movement of said lever under the strain ofvibration.

The lid 3 is clamped upon the section 2 by pivoted eccentric clamps 3. Ayoke 3 is centrally fulcrumed as at 3, to the section 2 at a point nearits top and it is fulcrumed at its ends as at 3 to opposite sides of thelid 3. The yoke 3 serves as a double hinge upon which the lid 3 is swungfrom its position upon thesection 2, of the cylinder A. The yoke carriesan angular extension 3, formed with a beveled end which bears againstthe side of the cylinder and serves to brace the lid when thelatter israised from the section 2, and assumes an approximately perpendicularposition.

The lid 3 is provided with a plurality, in this instance 4, of fillingnozzles 15, upon which the skins to be filled are secured, and in eachof said nozzles a valve is located to control the material fed from thecylinder, there being four such valves, designated 16, 16, 16, and 16,preferably of the turning plug type. It is permissible to increase ordecrease the number of valves employed according to the amount of workto be pro duced, without departing from the spirit of my invention, fourvalves being shown merely for the sake of clearness of illustration anddescription. Downward extensions 17, 17", 17 and 17 are carried by eachrespective valve. These extensions turn with the valve and aredetachably coupled as at 18 to complementary vertical rods, 19*, 19",19, and 19, respectively, sup ported in apertured brackets 20 carried bythe section 2.

The specific form of coupling employed to join the valve extensions 17etc. and complementary vertical rods 19 etc. is shown in Fig. 10, andcomprises an enlarged socket 18, carried upon the lower end of eachextension 17 etc. provided with frustum-shaped recesses 1S which receivean enlarged head 18 of corresponding contour to the said recesses formedupon the upper end of each of the rods 19 etc. These couplings duplicateone another in construction, so that the above description is equallyapplicable to all. Owing to the frustum shape of the socket and headreceived thereby, the rods 17 etc. and 19 etc. may be instantlyuncoupled without removing any parts or operating any extrane ousmechanism, but simply by lifting the lid 3 from the section 2. When theaforementioned rods are coupled together, the coupling 18 forms a rigidconnection, so that each of the rods 19 etc. are rotatable with thecorresponding valve and extension.

The vertical rods 19 etc. constitute one of the elements by which thevalves are operatively connected to the belt-shifting devices for themanual control thereof, the corresponding correlative elementspossessing the same index letter, so that in the following descriptionthe elements designated by a numeral and bearing the index letter acorrespond. In like manner those in each respective series possessingthe indices 1), c or (Z, are correspondingly correlative.

The specific means for shifting the belt from the fast to the loosepulley in stopping the operation of the various driving gear trains,comprises a series of horizontally alined vertical rods, one rod beingoperatively connected to each valve and being designated by numeralshaving corresponding indices as follows: 21, 21, 21, and 21.

The valve rods which I will designate detents are counterparts of oneanother in construction, so that a description of a single detent, asillustrated in Fig. 7 will suffice for all.

In the upper portion of each detent I provide a pair of superposednotches, the upper notch being designated 21, and the lower notch 21 Thelower end of each detent is beveled as at 21. A U shaped bracket formedintegral with the section 2, incloses all of said detents and coactswith other elements to form a common support therefor. A series ofbell-cranks are mounted upon a transverse rod 24, journaled in bearingscarried by the section 2, and correspond in number and arrangement tothe aforementioned de tents, these bell-cranks being designated 23, 23,23 and 23. The bell-cranks 23 and 23 are counterparts of one another inconstruction, so that a description of a single bell-crank asillustrated in Fig. 6, will suffice.

In their normal position, one of the arms of the bellcrank is disposedvertically, and the other arm is horizontally disposed. enlargedapertured end 23, and the horizontal arm 23 is beveled at its end toengage the notch 21 in the corresponding detent. The bell-cranks 23 and23, do not possess the enlarged apertured end 23 but otherwise theconstruction is the same as that of the bell- 25", 25 25 and 25,provided with an apertured end 25 by virtue of which the said rods areoperatively connected to the corresponding. bell-crank for operating thedetents. The rod .19 is positively connected .to the bell-crank 23 by atransverse rod 26, extending through a slot 27 in the section 2, andbent into a peculiar angular contour as shown in Figs. 1 and 3 to passaround the operating sprockets and screw, the said rod 26*, havingpivotal connection at its ends with the end 25 of the lever 25", andwith the end 23 of the bell-crank 23*. In like manner the lever 25 ispositively connected to the corresponding bellcrank 23 by a transverserod 26 extending through a slot 28 provided in the section 2, in whichslot the various operating bell cranks have a limited movement. I

The oppositely arranged levers 25 and 25 are each connected by acorresponding link 29 and 29 to corresponding levers 26 and 26, whichduplicate one another in construction. The levers 26 and 26, pos sess acurvature of about 90 degrees and are arranged adjacent the walls of thesection 2, being centrally fulcrumed as at 30, in a bracket formedintegral with the section 2. The rod 29* and 29, have pivotal connectionat their ends with the ends 25 of the levers 25 and 25, and with theadjacent ends of the levers 26 and 26, the other ends of the last namedlevers being secured to the ends of the bell cranks 23 and 23.

A bell-crank lever 31 is mounted at the junction of its arms upon ahorizontal rod 32 within the section 1, adjacent the beveled ends 21 ofthe detents 21 etc., one arm 31 of said lever 31 projecting through aslot 31 in the section 1. This arm 31 is equal in width to the combinedwidths of the beveled-ends 21 of the detents 21 etc., which rest and arenormally supported on said arm.

A weighted rod 31 is suspended from the other arm 31 of the bell-crank31 within the section 1. A rod 33 has its one end pivoted at 33centrally upon the arm 31 and its other end at 33 to a vertical lever34, pivotally connected at its lower end 34" to the bracket l The lever34 carries adjacent its upper end a laterally-extending yoke 35 Whoseedges overlap the sides of the drive-belt 4 The bell-crank 31 is shownin detail in Fig. 4, and comprises the automatic means for shifting thedrive-belt 4, from the fixed pulley 4, to the loose-pulley 4 thespecific operation of which will be presently explained.

Still another bellcrank lever 36 is mounted upon a horizontal rod 37,within the section 1, adjacent to the top thereof, and directly abovethe bell-cranks 3 etc. The bell-crank 36 is provided with a leg 36,having a beveled end and equaling in width the combined width of thedetents 21 etc. The other The vertical arm terminates in an end 36 ofsaid bell crank 36 is inclined upwardly ing of the turning plug type,can of course be turned and is engaged by the piston 12 in its downwardmovement for a purpose to be described.

In Fig. 5 of the drawings, I have illustrated the bell-crank 36 inperspective to show the detailed construction thereof.

The detents 21 etc., normally rest with their beveled ends 21 upon theends 31 of the bell-crank 31, and the beveled ends 23 of the bell-cranks23 engaging the notches 21 in each corresponding detent. In like manner,the beveled arm 36- engages the adjacent notches 21 in the detent.

In practical use, when the supply of material in the section 2 of thecylinder A becomes exhausted before the skins are filled, the operationis as follows:

When the clutch members 10 and 9 are engaged, the pinions 8 and 11 inmesh, and the screw 12 with the piston 12 is on the up-stroke, the pin12 will, at the termination of the upward stroke, engage the arm 13 ofthe frame 13 to reverse the direction of the travel of the said screw inthe manner previously described. At the termination of the down strokeof said screw, simultaneously with the action of the pin 12, in engagingthe arm 14 to set the gear train for the upstroke of the screw 12, thepiston 12 will strike the arm 36 of the bell-crank 36, thereby raisingthe arm 36 of said bell-crank, said arm being equal in width to thecombined width of all the detents, and lifting said detents 21 etc.synchronously from engagement with the leg 31 of the bell-crank 31. Thedetents having been thus lifted, the weight 31 will serve to draw backthe bell-crank 31 and the rod 33 therewith, thus drawing the lever 34towards the cylinder A and moving the yoke 35 to shift the belti fromthe fixed pulley 4, to the loose pulley 4, thereby stopping theoperation of the machine.

As long as the piston remains stationary in the position assumed at thetermination of its downward movement, the detents 21 etc. will be heldelevated by the bell-crank 36. At this stage of the operation, the lid 3may be lifted in the manner described, and the section 2 refilled withmeat.

When it is desired to start the piston upward, the lever 34 is pulledmanually outward against the tension of the weight 31 the yoke 35 beingmoved to shift the belt l from the loose pulley 4, to the fixed pulley4, to start the operation of the machine. As soon as the piston iselevated, sufficiently to release the bell-crank 36, the detents 21 etc.will fall by gravity back to their normal position upon the leg 31.holding the same against the tension of the weight 31 during themovement of the piston, and at the same time drawing the bell-crank 36into the path. of the piston 12 to be actuated in a similar manner onthe downward stroke.

On the up-stroke of the piston 12, the filling cocks 16 etc., are open,and the meat is fed from the cylinder into the skins fitted on thenozzles 16. As each skin is filled, the valve controlling the supply tothat par,- ticular skin is closed manually. Owing to the manner in whichthe valves are connected, as shown in the drawings, it is necessary toturn the adjacent pair of cocks 16 and 16 to the right, and the adjacentpair 16 and 16 to the left, in order to actuate all of the bellcranks 25etc. in the same direction. The valves bein either direction asnecessary.

When the skins are all filled, before the supply of material in thecylinder A is exhausted, the operation is as follows: Assuming that thefilling cock 16 is first closed, the valve being turned to the right thecomplementary rods 17 and 19 and rigidly secured lever 25 will berotated in the same direction, and will draw back the rod 29, therebyimparting a limited oscillatory movement to the lever 26 to move thebellcrank 23, causing the arm 23 of said bell-crank to lift the detent21 from its normal position upon the .arm 31 of the lever 31. Let thecock 16 be the second one to be closed, and be turned in the samedirection, 11. e., to the left as was the cock 16. The rods 17 and 19,and rigid lever 25 will rotate therewith, drawing back the link 29,swinging the lever 26 upon its pivot 30 to draw back the bell-crank 23,and lift the detent 21. The filling cock .16 being next closed, andmoved to the left as set forth, the rod 26 will be drawn back, and movetherewith the bell-crank 23 to lift the detent 21 in the mannerdescribed above. The filling cock 16 we will say is the last one to beclosed, it being also turned to the left and pushing toward the rod 26to actuate the bell-crank 23, to lift the detent 21 in the same mannerthat the filling cock 16 lifts detent 21 Thus, when all the valves, areclosed manually, the detents are all lifted, one by one, from the leg 31of the bell-crank 31, allowing the belt-shifting mechanism to operate inthe manner above described. The piston 12 will thus be stopped in itsupward movement before the completion of its travel, and the skinsalready filled may be removed from the filling nozzles 15, and replacedby empty ones. The belt-shifting lever is then drawn outward to placethe belt upon the drive pulley, and the cocks are manually opened, thevarious actuating rods being thereby moved in the reverse direction todraw forward the bell-cranks 23 etc., and lower the detents upon the leg31 of the bell crank 31, the operation of the machine from this pointbeing the same as previously described.

It is obvious that many minor changes may be made without departing fromthe spirit of my invention.

I do not limit myself to four filling cocks, but show and describe thisnumber for the sake of convenience, as any desired number couldobviously be used by making slight changes in the connecting rods andlevers.
